Pager motors and robot gearmotors

Didel is well known for his choice of 4mm to 7mm pager
motors with different resistance, that is different power.

We have now invested in gears and electronic to have the best robot motor
for 200-1kg robots and many other applications

Electric motors need a gearbox, A reduction ratio betweem 20 and 100
is the best

It is rather easy to remove a motor from a toy, sometimes with the gears,
but before making a robot around reused parts, check the voltage, the
power and the noise. Motors with a reasonable current are mentionned "solar
motors"

For playing with robots, look at the motor and gears used on CD to extract
the disk. They are well designed, motor is usually 12V, but you may get
enough power from a 5V supply.
